Forum: audio Subject: Recent change in search wildcards?

It seems wildcards in search strings no longer work as they did; for example, a string with "?" characters now seems to offend the search engine in the archive. An example is the "Grateful Dead shows on this day in history" link on the Grateful Dead page (http://archive.org/details/GratefulDead); this generates the search string "http://archive.org/search.php?query=collection:GratefulDead%20date:19??-12-04&;sort=-/metadata/date", which results in an error from the search engine: "The search engine encountered the following error: Search engine returned invalid information or was unresponsive. We are working to resolve this issue. Thanks for your patience."

Did something change recently? (This seems to have been happening for about a week.)

Yes, the search engine was recently updated. I'll send the search guru here and he should be able to help further.

Hi Jon and greenone,

yes, that was me (the girl guru of expanded 2 person search team here at IA)
who did the change when we did an update of our search engine that was 4+ years old.

unfortunately, a few features like using "?" chars and sorting on "multiValueds" (ie: sorting on field "updatedate") stopped working.

the best workaround I could find was to alter the query slightly and use the title. I did this for the JS "This day in history" link on the main LMA/etree page, too.

so this should be quite close to what you were using before (I realize it will additionally also show 20?? shows, as well, but figured that's prolly OK?)

http://archive.org/search.php?query=collection:GratefulDead%20title:%22-12-04%22&;sort=-date

sorry for that -- we got a huge amount of good w/ the update, speed *especially*, and lots of new features. but we lost a few -- some of which hit me by surprise and were totally unexpected!

Hi Tracey,
thanks for the reply. Unfortunately, I have an Android app (The Dead Of The Day) that uses the wildcards to select shows from the same day, week or month as the current one (and widens its search successively if it doesn't get results - day, then week, then month, then any date). Is there a new wildcard syntax that will allow for this sort of search? In fact, is there any documentation for the search syntax accepted by the new search engine?
Thanks,
\
Jon

Hi Tracey,
I think I found a workaround that works for me - using truncated date strings seems to be sufficient for what I need, and seem to be accepted by the search engine. For example, "date:1977-05-" will return all the concerts for May 1977.

I'd still like to make sure this is a standard approach that the search engine will accept, so if you have any docs that describe the search syntax that would be greatly appreciated.

Thanks,
\
Jon

That will work!

See bottom of the advanced search page link found on most pages to see some syntax examples and links
